The vulnerabilities are based on the CVE vulnerability naming standard and are organized according to severity, determined by the Common Vulnerability Scoring System (CVSS) standard. The division of high, medium, and low severities correspond to the following scores:

High – Vulnerabilities will be labeled High severity if they have a CVSS base score of 7.0 – 10.0

Medium – Vulnerabilities will be labeled Medium severity if they have a CVSS base score of 4.0 – 6.9

Low – Vulnerabilities will be labeled Low severity if they have a CVSS base score of 0.0 – 3.9

In Apache Karaf prior to 4.2.0 release, if the sshd service in Karaf is left on so an administrator can manage the running instance, any user with rights to the Karaf console can pivot and read/write any file on the file system to which the Karaf process user has access. This can be locked down a bit by using chroot to change the root directory to protect files outside of the Karaf install directory; it can be further locked down by defining a security manager policy that limits file system access to those directories beneath the Karaf home that are necessary for the system to run. However, this still allows anyone with ssh access to the Karaf process to read and write a large number of files as the Karaf process user.

In Apache Karaf version prior to 3.0.9, 4.0.9, 4.1.1, when the webconsole feature is installed in Karaf, it is available at …/system/console and requires authentication to access it. One part of the console is a Gogo shell/console that gives access to the command line console of Karaf via a Web browser, and when navigated to it is available at …/system/console/gogo. Trying to go directly to that URL does require authentication. And optional bundle that some applications use is the Pax Web Extender Whiteboard, it is part of the pax-war feature and perhaps others. When it is installed, the Gogo console becomes available at another URL …/gogo/, and that URL is not secured giving access to the Karaf console to unauthenticated users. A mitigation for the issue is to manually stop/uninstall Gogo plugin bundle that is installed with the webconsole feature, although of course this removes the console from the …/system/console application, not only from the unauthenticated endpoint. One could also stop/uninstall the Pax Web Extender Whiteboard, but other components/applications may require it and so their functionality would be reduced/compromised.

Apache Mesos can be configured to require authentication to call the Executor HTTP API using JSON Web Token (JWT). In Apache Mesos versions pre-1.4.2, 1.5.0, 1.5.1, 1.6.0 the comparison of the generated HMAC value against the provided signature in the JWT implementation used is vulnerable to a timing attack because instead of a constant-time string comparison routine a standard `==` operator has been used. A malicious actor can therefore abuse the timing difference of when the JWT validation function returns to reveal the correct HMAC value.

A denial of service vulnerability was identified that exists in Apache SpamAssassin before 3.4.2. The vulnerability arises with certain unclosed tags in emails that cause markup to be handled incorrectly leading to scan timeouts. In Apache SpamAssassin, using HTML::Parser, we setup an object and hook into the begin and end tag event handlers In both cases, the “open” event is immediately followed by a “close” event – even if the tag *does not* close in the HTML being parsed. Because of this, we are missing the “text” event to deal with the object normally. This can cause carefully crafted emails that might take more scan time than expected leading to a Denial of Service. The issue is possibly a bug or design decision in HTML::Parser that specifically impacts the way Apache SpamAssassin uses the module with poorly formed html. The exploit has been seen in the wild but not believed to have been purposefully part of a Denial of Service attempt. We are concerned that there may be attempts to abuse the vulnerability in the future.

In Apache Tika 0.1 to 1.18, the XML parsers were not configured to limit entity expansion. They were therefore vulnerable to an entity expansion vulnerability which can lead to a denial of service attack.

In Apache Tika 0.9 to 1.18, in a rare edge case where a user does not specify an extract directory on the commandline (–extract-dir=) and the input file has an embedded file with an absolute path, such as “C:/evil.bat”, tika-app would overwrite that file.

Artifex Ghostscript before 9.25 allowed a user-writable error exception table, which could be used by remote attackers able to supply crafted PostScript to potentially overwrite or replace error handlers to inject code.

blocking_request.cgi on ASUS GT-AC5300 devices through 3.0.0.4.384_32738 allows remote attackers to cause a denial of service (NULL pointer dereference and device crash) via a request that lacks a timestap parameter.

A CSRF vulnerability in the Runtime Config component of Avaya Aura Orchestration Designer could allow an attacker to add, change, or remove administrative settings. Affected versions of Avaya Aura Orchestration Designer include all versions up to 7.2.1.

A cross-site scripting (XSS) vulnerability in the Runtime Config component of Avaya Aura Orchestration Designer could result in malicious content being returned to the user. Affected versions of Avaya Aura Orchestration Designer include all versions up to 7.2.1.

Bitcoin Core 0.14.x before 0.14.3, 0.15.x before 0.15.2, and 0.16.x before 0.16.3 and Bitcoin Knots 0.14.x through 0.16.x before 0.16.3 allow a remote denial of service (application crash) exploitable by miners via duplicate input. An attacker can make bitcoind or Bitcoin-Qt crash.

A directory traversal vulnerability in the Connect Service of the BlackBerry Enterprise Mobility Server (BEMS) 2.8.17.29 and earlier could allow an attacker to retrieve arbitrary files in the context of a BEMS administrator account.

An issue was discovered in Browserify-HMR. Attackers are able to steal developer’s code because the origin of requests is not checked by the WebSocket server, which is used for HMR (Hot Module Replacement). Anyone can receive the HMR message sent by the WebSocket server via a ws://127.0.0.1:3123/ connection from any origin.

An issue was discovered in CIRCONTROL Open Charge Point Protocol (OCPP) before 1.5.0, as used in CirCarLife, PowerStudio, and other products. Due to storage of credentials in XML files, an unprivileged user can look at /services/config/config.xml for the admin credentials of the ocpp and circarlife panels.

Cloud Foundry Container Runtime (kubo-release), versions prior to 0.14.0, may leak UAA and vCenter credentials to application logs. A malicious user with the ability to read the application logs could use these credentials to escalate privileges.

Cloud Foundry Garden-runC release, versions prior to 1.16.1, prevents deletion of some app environments based on file attributes. A remote authenticated malicious user may create and delete apps with crafted file attributes to cause a denial of service for new app instances or scaling up of existing apps.
